Jon
Attorney - criminal defense
Every time I think I had a bad day, I remember that there are a frightening number of people who’d trade their good day for my bad one. That helps me stay humble and grateful.
Sean
PERSONAL INJURY LAWYER
Sean O’Sullivan was born and raised in Jacksonville…
Sean O’Sullivan was born and raised in Jacksonville, Florida. Upon graduating from Bishop Kenny High School, Sean attended Florida State University, where he completed a double major en route to earning his bachelor’s degree. Sean then went on to earn a law degree from the University of Miami School of Law before returning to Jacksonville to begin his legal career.
Sean started his career working for a statewide insurance defense firm, and his practice focused on defending insurance companies and their policyholders against personal injury claims, including cases involving automobile negligence, premises liability, medical malpractice, and wrongful death actions. As a result, Sean gained invaluable insight into how big insurance companies operate, from pre suit negotiations all the way to litigation and trial.
After spending over three years defending big insurance, Sean began practicing personal injury law in 2016. Now he exclusively helps those who have been injured due to the negligence of others. Sean strives to be compassionate and is committed to providing clear communication with an aim toward achieving maximum and—most importantly—just compensation for all of his clients.
In addition to helping injured individuals and their families, Sean enjoys golfing and cheering on the Seminoles and Jaguars. Most importantly, Sean loves being with his own family. He and his wife, Kimberly, have three sons, including identical twins.

Violeta
Case Manager
After working with insurance companies for 5 years and seeing first hand how uncaring they were towards their insureds and victims. I decided to leave and work where I would make a difference in people's lives. This change gave me the opportunity to learn about personal injury. I have been a Personal Injury case manager for 8 years and love helping our clients get their health back and get the compensation they deserve.
